The disk's noise was two sin() terms (phi*8, phi*23) producing geometric bands. Replace with domain-warped FBM: a 3-octave value-noise field warps the sampling coordinate of a 4-octave FBM, giving the feathered/smoky gas texture of the Gargantua reference. The Keplerian shear (rot ∝ 1/r^1.5) is retained as the flow time term so inner radii rotate faster.
